Abstract

Polymer processing involves complex flows in which the material is submitted to shear and elongational deformations. The rheological behaviour of polymers is (i) time-dependent (i.e the fluid “remembers” what happened to it before) and (ii) highly non-linear (i.e dependent on the amplitude of the deformation) at large strains. So basic rheological measurements have to be carried out in simple flow geometries if one wishes to define precisely the relationship between the structure (chemical structure, molecular weight...) and the rheological behaviour (hence the processability) of the material.
